BPCUtility Brushes, 16.5”, 2 Pack, Skinny, Flexible, but Sturdy Curved Bristles to Clean Vase, Wine, and Kombucha Bottles with Openings 1” up Plus Machinery Wherever a Long Reach is Needed.

These brushes are overall pretty good. Ive used them to clean out lab glassware and they did the job.Only complaint is the metal part that the brush is attached too is pretty close to the surface of the bristles.That can scratch the glass so you have to be careful when using them.The metal also isn't stainless so it'll start rustic eventually. The bristles are pretty stiff, in my case I needed that.But its something to keep in mind if you need softer bristles.

The wire itself was just too thick for my purposes. Measure well if you need precision.

I was looking for a tool to help me clean out a humidifier. I wanted something sturdy yet flexible. I was hesitant to purchase this brush for fear of wasting my money, but I am so glad I did! I was able to move the brush into many different positions to clean the humidifier. It worked wonders!

Great for cleaning live rock in my aquarium.

These are great little bottle brushes, I like that the tip also has bristles on it to be able to clean the bottles well. The only thing I would change is to have a set of 3 sizes so that it would be more useful for more bottle sizes. I had originally gotten this to clean humming bird feeder bottles but it is too large to fit in the bottle but I use it to clean other bottles.

I've been searching for a long handle very thin brush to clean the inside of hummingbird bottles. The very tip of this is coiled over and keeps it from being able to go through the opening. With force we were able to uncoil the tip so it will go through the opening

Purchased to clean blue cobalt quart size bottles (similar to wine bottle). Had to pinch the top a little more narrow with pliers to get it to go inside the neck of the bottle. But once inside it does what it's supposed to do.

Reaches down into the dryer vent to clean out the lint but it's pretty flimsy and bends easily. I wish the wire was just a little stiffer.
